Anyone can own a dog. This is where you become a handler. Most dog-training apps give you part of the science. K-9 Handler Academy gives you all of it — how dogs really learn — with professional AI coaches you talk to, who tell you what's working and what to fix. Built for anyone ready to stop guessing, and to use the right tool for the job. YOUR AI COACHES Describe what you're working on and get precise, immediate guidance — grounded in operant conditioning, marker timing, drive, and threshold management, not ideology. Building foundations or troubleshooting a problem behavior, your coach meets you where you and your dog actually are. Speak and they answer out loud, so you can keep your hands on the leash and your eyes on your dog. Maya coaches in the moment — direct, practical, focused on what to do next. Gus goes deeper, explaining the mechanism before the fix, so you understand why your dog is doing what they're doing. THE COMPLETE SCIENCE Rewards, pressure, and consequences — the full picture of how dogs learn, each explained in plain language and used correctly. No dogma, no skipped chapters. You'll understand not just what to do, but the mechanism underneath it. STRUCTURED BELT PROGRESSION A real curriculum, White through Red, each belt built on solid fundamentals before you advance. No shortcuts — just measurable progress you can see. SESSION ANALYSIS Log a session, get AI analysis of what worked, what didn't, and exactly what to drill next. Your training, made accountable. SKILL BUILDER Step-by-step drills for the skills in the curriculum — timers, technique cues, and feedback on your execution. MULTIPLE DOGS Train more than one dog on a single account. Each dog has their own profile — drive, reactivity, motivation, date of birth — and their own training record, so what one dog has learned doesn't show up on another's. Switch between them in a tap, and archive a dog you're no longer training without losing their history. HANDLER-FIRST The dog reflects the handler. We train you first — your timing, your mechanics, your consistency — and the dog follows. Built on Dr. Dmitry Nikelshpur's methodology, drawn from the science of how humans and animals actually learn. Free, Pro, and Elite tiers, with credit top-ups available anytime. Founding Member pricing for early adopters. Terms of Use (EULA): https://drdmitrydoghandler.github.io/k9-legal/terms.html Privacy Policy: https://drdmitrydoghandler.github.io/k9-legal/privacy.html

Verdict

The call

The clearest difference is review sentiment: K at 100% against CNA Practice Exam Prep's 50%. K also leads on update cadence (every 5 days vs every 2 months) and rating (5.0 vs 4.6). CNA Practice Exam Prep's advantage is ratings volume (213 vs 1) and iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and monetization model there is nothing between them.
